My 11 year-old son and I are having a major debate regarding the differences in the Playstation2 Slim and the Playstation2! My son continues to tell me that there are several upgrades, and wants to purchase a PS2 slim! The only difference besides being slimmer) that I can come up with is that there is an ethernet connection for online gaming, which he is not really into. I have been to several websites and can’t find direct comparisons. Is this just a waste of money, or are there some real differences. What about the PS3?? Wouldn’t this be a better decision? Help!
